Jpi's are usually pretty accurate. I don't believe your number six could be that much cooler than the rest. A way to check the probe is to switch it with any of the other probes and see if the cool cylinder follows the switched probe. Check back after that experiment.

I agree with Skip on checking. If the low temp stays with the cylinder - it can also be a placement issue. Recently had the exhaust stacks overhauled which caused all the EGT holes to be re-drilled. Same engines, no other changed but the EGTs on the JPI became much more consistent due to the more consistent distance to the cylinders.
